Appncaiion med :une es,` `1921. serial No. 431,062.`

To alt whom it may concern.; Be itknown that I, HEINRICH Roivrnnne,

engineer, a citizenof Germany, residing at Dsseldorf, Germany, 25 Parkstrasse,` have invented `certain new anduseful Improvements in RecoilGruns, of which thefollown ynions b are introducedinto the bearings@ provided on the platform and secured there, j l i j' ing is a specification.

The present invention has for an improvement of airecoill gun. In this l0 gunfor securingyand carrying` thebarrel and :the cradletwo points" of support are provided andfor this purpose at the for- `ward part betweenlthefbase plate and the e i barrel7 the elevating device, and at the rear `1`51part,` the axles ofthe trunnions,` are i arranged. Infthis instance the axis of the trunnions, is disposed sofar aftthat it will be situated even behind therecoiling parts,

when 'the `latter v have j' travelled farthest fbackwards, and it remains in close prox` imity to` the `bottom plate. By this arrangement of the two supporting points the forward part of the "barrel will alwayshe higherthan the axis of the trunnion, be-

cause the elevating' device will lrequire j a` larger space, j. In consequence, no directfring "is possible.' w j i. j

Through the present `invention thisk ydis-` i advantage is eliminated,` so that the gun may beused both for direct and indirect firing.

The invention for that purpose makesv use ofthe means `known in other guns,` that the bearingof the trunnionsmay be variedin its height,vconsist`s ofalsimple and easily ma'- nipulated device in which betweenvthejboto tom plate and the trunnions offtheybarrel g an intermediate memberis interposed, that j is provided with two `journalbearings, one

` "of whichl is adapted for the reception of the trunnionsywhilethe other serves for secur-` ing to thebottom' lateso that the barrel may be swung into t e horizontal. Both the journal bearings of the intermediate member `may may v,alsofbe connected to `each 1 other bymeans' offa longitudinal slot.

Inv the drawing several modifications of the invention are shown.

` j -The barrel a is .accordingto Fig; lmov-I able `in afwell known manner within the 50 cradle aeanddisposed` on the base plate or platform e in two supporting points. One.

of these supporting points is constituted by the elevating device f and provided at the forwardor central part of the barrel. The other'supporting point is constituted by the 'ag abject` ner, that the the recoiling j their farthest way backwards.

During steep or indirectffiringthe trunso that the'trunnionsrest in close proximity to the platformv e.` Inorder to: permit of direct firingand of `dipping and turning lower` yet theintermediate member d is in` troduced between theplatform e and `trun- H nions b. This intermediate memheral'iszprovided with two or more journalk bearings 7L,

4the barrel a, with its cradle tothe' h orizontah 1 plane in respectof the platform,` or even [2,1 of which the bottommostubearingfh is secured in the bearings@ while thetopmost j bearing t serves forthe"` reception of the trunnionsb. e i .j

Fig. 2 shows another modiiication" ofthe invention. Herethe intermediate member possesses a longitudinal slot g" instead of` holes or" bearings tpkl in which slot the j bearings clor` the" trunnions b may besecured at a `varying height.`

Fig. :3 represents `a different `(.:onstructi'on in so far as here the intermediate memberi is shaped into a trail .ofa gun carriage possessing a spur k, so thatstability ofthe j gunis securedwhile theparts are ,recoiling.

In the lconstruction as shown in Fig; 4'

an arrangementof levers is substituted for the intermediate member d. By shiftingthe i lever` Z into the position shown in "dotted A `lines a collapse of the joints `naa is effected i `which will cause the barrel cr to movefinto j the position shown in dotted lines, that is to say into the position for indirect 1iring,whi1e i by putting down thelever Zthe joints m, fn,

are raised withthe supporting levers o,wp,.`

raising thus the trunnions bV in such a mangun` may be used for "direct firing. e i i. A
